w e eas we we are 68W?- To all whom it may concern:

Be it known that I, Annnnnnr L. GARDNER, a citizen of the United States, residing in the city of Chicago, Cook county, Illinois, have invented new and useful Improvements in liIeat-Slicing Machines, of which the'following is a specification.

My invention relates to improvement in meat slicing machines, in which ahorizontally reciprocating carriage having an automatic feed device attached thereto operates in conjunction with an upright circular r; tating knife, and the object of my improvement is to provide means whereby to slice the meat from the rind, leaving said rind to be removed from the uncut remainder as desired by the operator. 2

Heretofore it has been observed that an improvement was desired over the old way of removing the rind from apiece of meat by hand, and means have been provided for doing this automatically and during the slicing operation in order that the rind may be left on the meat as long as possible to better preserveit from contact-with the air. It has been unavoidable however that after the first slice has been taken from the meat there is left an exposed raw surface, while at the same time the separated rind has been cut by the slicing knife into narrow strips, making it unavailable as a covering for such raw surface, and of no practical value as a salable product, or for any other purpose.

One of the objects therefore of the present invention is to provide means used in connection with a meat slicing machine for separating the rind from the meat without cutting or injuring it in any Way, but leaving it attached to the meat at one edge in order.

meat remains unsliced, such remaining part may be turned about and slices taken fromits opposite end, with the attached rind used to securely fix it upon the meat platform by placing a fresh piece of meat upon it and clamping it down. 7

A device embodying the principles of the present invention is illustrated in the acc0mpanying drawings in which:

Figure l is a side view of the machine with improvements attached. Fig. 2 shows a vertical transverse section through the carriage and machine frame on the lines A--A of Fig. 1. Fig. 3 is a vertical sectional view of the adjustable guide improvement. Fi 4 is a rear view of a section of the rod 2 Fig. 5 is a transverse vertical section through the horizontal shaft 23' supporting the rind stripper.

vAs shown in said drawings the complete machine comprises a suitable base frame indicated as a whole by at, having at one side a column or standard 2 in the upper art of which is journaled a circular rotary linife 3 partly incased by a shield or guard 4. The

ase frame a is formed to provide a level top surface upon which is mounted a reciprocating meat carriage 5, with a flat top 14;, am ranged to move in a plane parallel and adjacent to the cutting plane of the knife 3, in prcler that the meat which is carried upon it may be sliced by the circular knife; and supported upon the meat carriage 5 is also a slide or shelf 12 which is adapted for feeding forward, as viewed in Fig. 1, in order to supply fresh portions of the meat to the knife 3 as the s ices are taken off. Upon the slide 12 ise'rected a frame comprising vertical posts 6, and a movable, toothed horizontal bar 7 for securely fastening the meat to the slide; the two posts 6 having notches for engagement respectively by a hookshaped part or notch on one end of the horizontal bar 7 and a movable pawl 8 at its other end; and the latter end being extended in the form of a handle for convenient manipulation. The knife 3 is rotated through a chain and sprockets, a horizontal shaft,

and gearing,

diagrammatically in "dotted outline, and

balance wheel 10 with a handle 11 by means of which it is rotated. Means are also pro 'vided for reciprocatingly moving the carand left as viewed in;

riage 5', to the right Fig. 1, and for feeding the slide 12 forward A curved pan 9 is also provided for receiving the slices of meat which fall from the end of the carriage 5.

I a All of the foregoing parts of the device are made in accordance with well known beadjusted toward or .inconnection with the slicing the meat; but as here shown the knifeis separated some rinciples. 7

The cutting lane of the knife lies somewhat forward of the front vertical wall 22 'of the base frame a, and the flat'top 14- of the" meat carriage 5; overhangs this wall.

somewhat. In the usual construction the flat top of the meat carriage forms a shear knife for properly little distance from the edge of the meat carriage and pose of properly meat to be sliced and to form a shear in connection with the rotary lknife an adjustable plate 15 is placed upon-the flat top it of the carriage 5 between the latter and the slide 12 and such adjustable plate is formed with a forward vertical wall plane of the knife; such shaft 18 being j ourprevent it from naled in a fixed lug 20 depending from the 14: of the carriage and having a thrust collar 21 on its inner end and a hand wheel 19 on its outer end. The lug 16 is accommodated in a slot 17 through the top 14,

such; slot serving to limit its movement and being brought into contact with the slicing kmfe.

the forward edge of ofseparating the rind the slicing operation a wedge-shaped rind stripper 30, which is fixed 'to the. upper end of a longvertical, square shank 27, is supported adjacent to the meat supporting plate 15, such stripper being shaped to provide a thin rear edge which will wedge apart the rind and the meat when the latter is fed forward and moved from side to side; and the underside of such stripper is curved in order to turn the rind downward, as indicated in Figfdwhere the rind is shown in dotted outline at 39. In the top part of the stripper 30 is cut a groove in which is fitted a sliding strip or point 37, made adjustable by means of a screw 38 according to the desired depth to which the stripper is to be For the purpose from the meat in not here shown but indicated t0: 'one end of such horizontal shaft is fixed a" '30 with its vertical upon the machine by collar 24: which is bolted to the forward verthreaded sleeve or for the pursupporting the part of the' the slicfrom the cutting forced into the material. The rind stripper means of a ange tical wall 22 of thebase frame a. Throufgh v 3 this collar extends a horizontal shaft which projects throughan' opening through concentric with the collar aid the wall 22 is'provided with a nut or collar d on fs inner end.- The'outer end of the collar 241s internally threaded shank 27 is sup orteg one end against the end of such sleev j 'y' and at its other end against a flange or col-' lar 0 which is pinned to the shaft 23. The

collars or flanges 12 and d are spaced suffb' .ciently apart to allow drawn outward against the force of the spring 36. A fixed collar or nut 34; is also secured to the outer end of the sleeve j'and' the outer end of the shaft 23 is screwed into an elbow 25-which has a threaded part fixed into the lower end of a vertical tube 26 by means of a small set screw 39. This tuloe supports thevertical shank 27 of the rind the shaft 23 to be stripper, and from the foot of such tube extends a lug 35 adapted to engage in one of two notches k, k, in the fixed collar 34: for the purpose of securing the rind stripper in either a vertical or horizontal position; .11:

may be adjusted into either of such posi tions by drawing it outward against the ten- '1 sion of the spring 86 to disengage the lug 35 from its notch and then rotating it through 90 into its other position. The upper end of the tube 26 is threaded and over its top is screwed a cap 29 having a square 0 emng therethrough square shank 27 of the rind stripper. urrounding this shank and within the tube 26 is a coiled spring 31 bearing upon a collar or flange 28 at the lower end of the shank and pressing it shank resting upon the upper end of a long through which exten s the downward; the lower end of the screw 32 which is threaded upward through an opening through the elbow 25. By means I i of the screw 32the rind stripper is vertiprovide for its cally adjustable in order to proper cooperation with the adjustable supporting plate 15. Somewhat below the cap 29 the shank 27 is reduced in'diameter and, made cylindric, as shown at 33, so that by drawing it upward until thecylindric part is within the opening through the cap 29 the shank may be rotated in order to turn the rind stripper away from the meat when desired.

In the operation of the device the meat is placed upon the sliding platform 12 and the machine operated in the usual manner, when the rind stripper 30 will be forced between the rind and the meat in the forward feeding of the latter and its reciprocating sidewise movement and will act to direct the 75 and into it is fix'ed;a i j tube y; and within the collar 24 is arranged a spring36 bearing-S t U secured to such front wall,

detached rind downward and withhold it from the cutting knife. The proper relation of the partsmay be obtained by adjusting the adjustable supporting plate 15 forward or backward, by varying the height of the stripper through the screw 32, and by adjusting the length ofits point through the screw 38. The hei ht of the stripper is adjusted according to t e thickness of rind, and in addition, by the yielding of the spring 31, it can accommodate itself to irre ularities in such thickness. When dethe entire stripper may be rotated about its horizontal shaft 23 into a horizontal and inoperative position.
